Application filed October 2, 1917. Serial No. 194,323.

To all whom it may concern:

Be it known that I, \VALTER BUswELL, a residing at Germantown, Philadelphia, in the county of Philadelphia, and State of Pennsylvania, have invented new and useful Improvements in Box-Covering Blanks, of which the following is a specification.

The present invention. relates to certain novel and useful improvements in box covcring blanks of the character shown and described in the Patent No. 845,205. dated granted to J. S. Stokes. The box covering blank forming the subject matter of said earlier patent embodies a sheet of thin, flexible material. having integral side wings provided with end lap projections adapted to be folded around the box corners, and small corner staying tabs consisting of separate pieces of staying material attached to each wing and its extensions and positioned thereon over the corner folding lines to set the corner joints of the box shell, the blank itself when applied to the .s'h-elkcompletely covering the bottom and side walls thereof. This style of box covering, blank may be used to great .advantage under ordinary conditions for covering and staying box shells, but under certain special conditions difiiculty may be encountered in successfully employing such blank. For instance, in covering an .extremely narrow box with such a blank, particularly where a box covering machine is employed for applying the b ank, it is difficult to put the two pairs of oppositely arranged staying tabs on the blank body, because the width of the blank is not sufficient to allow the machine to operate successfully I aratc tabs, one

'diflicult to place,

in applying the transversely opposing tabs. Furthermore, such earlier box covering blank requires the application of four sepfor each corner, these tabs being relatively small, and in some respects,

and-in addition, no provision is made in such blank for reinforcing ing between transversely opposing tabs.

In the present instance I propose to obviate the disadvantages incident to such a blank by employing but two relatively longv staying strips in the place of four separate tabs, thereby permitting the ready application of the same by the box covering maline or crease extend chine, these stay strips overlying certain folding lines of the blank body so as to not only stay the joints of the box shell, but also to reinforce the transverse edges of the covered shell.

It is also my purpose to provide a stayed box covering blank which will embody the desired features of simplicity and efficiency and which may be produced quickly and economically and-applied to the box shell in such manner as to not only strengthen the corners ofthe latter but also to strengthen the ends thereof.

Vith the above recited objects and others of a similar nature in view, my. invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings:

a Figure l is a perspective view of box blank embodying my invention and having the stay strips applied thereto.

Fig. 2 is a perspective view of one of the stay strips adapted to be pasted to the body of the blank.

Fig. 3 is a perspective view of a box shell with my improved cover blank par-' tially applied thereto.

Fig. 4 is a sectional view taken on the line 44 of Fig. 1. p

Fig. 5 is a vertical longitudinal sectional view taken through covered box on the line 5-5 of Fig. 3.

Fig. 6-is a similar view taken on the line 6-6 of Fig. 3. y

Referring now to the accompanying drawof one form one end of the partially ings in detail the numerall indicates the "body portion of the blank which is shaped to' correspond to the size and shape of the top or bottom of the box to be covered.

This body portion is provided with end.

flaps or wings 2 and side flaps or wings 3. The stay strip employed in the present instance ;is indicated by the numeral 5 and is' in the nature of a relatively long strip of strong or tough but flexible material, such as manila paper,'muslin or any other suitable fiexible material, and two of these strips are employed, each having one face.

thereof completely covered or coated with an adhesive 6 so that in applying the strip the adhesive face thereof is placed in contact with the blank body and sealed or pasted thereto, as shown in Fig. 1. In the the blank and the side and en .box is machine or hand covered.

application ofthe strips to theblank bodythe are placed transversely of the latter adjacent the end of the body so as to overlie t transverse folding lines "7 of the blank. fter the strips have been applied to the blank, both the strips and the blank may benotched as shown at 8 to form the usual end laps 9 on the side flaps or wings 3, these end laps being reinforced by the corner tab sections 1001? the staying strip 5, and which sections are of course formed in the notching operation. In the operation of applying-this cover blank to the box shell, the uppermost face of the blank, or that on which the stay strips are pasted is coated throughout with an adhesive. The top or bottom of the box shell, as the case may be, is then centered upon the body ortion 1, of I wings 3 of the latter are then folded up and applied to the side andend walls of the box either by a machine or by hand, accordingl as the The free, marginal edge portions of the side andend wings may of course be folded in against the 1nner faces of the walls of the box shell, as will be readily understood by reference to Fig. 5. It will be noted that in the application of the cover blank to the box shell the former will be folded along the transverse folding lines 7 so that the crease or fold will run centrally and longitudinally of the stay strips, thereby causing both the transverse ends or edges and the corners of the box shell to be thoroughly protected and reinforced, and naturally these'strips also strengthen or reinforce the cover blank itself at the points where it is subjected to the greatest amount offwear and tear when applied to the box, that is along the corners and edges. 7

While I have herein shown and described one particular embodiment of my invention, I wish it to be understood that I do not confine myself to all the precise details of v construction herein set forth by way of illustration, as modification and variation may be made 'w1thout departing from the spirit 1. As a new article of manufacture, a box v covering and staying blank comprising a body portion having integral side and end wings, and end laps at opposite ends of the said side wings and adapted to be foldedabout the box corners, and notched staying strips of reinforcing material arranged transversely of the blank adjacent opposite ends thereof and extending throughout the major portion of the width of the blank and overlying transverse folding lines of the blank whereby to reinforce the vertical corners and the transverse end edges of a box to which the blank is applied.

2. As anew article of manufacture, a box shell covering and staying blank comprising a body portion having integral side and end wings, said side wings being notched-at 'opposite ends to provide end laps at such ends ofthe side wings, which laps are adaptedto be folded about the box corners, and a pair of staying strips of reinforcing material adhesively attached to the upper face of the blank and extending transversely of the blank adjacent opposite ends thereof and v overlying transverse folding lines of] the blank, said staying strips having notches,

coinciding with thenotches of the side wings to provide end tab sections reinforcing the corner joints of the box shel'l, the

intermediate sections of the reinforcing strips reinforcing the end edges of the box shell.

3 As a new article of manufacture, a box shell covering and stayin blank having adhesively attached to one ace thereof a reinforcing strip having end sections adapted to constitute staying taps for opposite corners of a box. shell and an intermediate section adapted to constitute a reinforcement for the edge 'of the shell extending between the corners stayed by the tabs.

In testimony whereof I have hereunto set my hand.
